A Rage for Revenge(1989)

David Gerrold

Still reeling from the alien plagues that killed two-thirds of the planet's population, humanity now confronts the most deadly enemy Earth has ever known - the giant man-eating Chtorr. Lieutenant James McCarthy has grown to manhood under the shadow of the terrifying invasion of the Chtorr. As a student, he learned all he could to understand their alien behavior. As a Special Forces commando, he made violent first contact. Now this battle-hardened warrior faces a profound challenge. Captured by an anarchistic band of men and women known as renegades, McCarthy must secretly gather vital information while fighting indoctrination into their cult - which serves and worships the Chtorr.
